Systems and methods for UE state machine to support multiple services or air interfaces are described. The UE may have one configuration of the state machine for multiple services or air interfaces. The UE may have multiple state machines for different services or air interfaces that work independently. The UE may have multiple state machines for different services or air interfaces that work collaboratively. The UE may have a state machine that uses a state machine configuration selected out of a plurality of state machine configurations according to the services used. The configuration of this state machine may be adapted to services. At initialization, the configuration of this state machine may be default or be determined according to the services the UE may use. During operation, the configuration of this state machine may change according to the change in services for the UE.
